When NaCl (salt) is added to water, the correct responses are:
-
separates into ions - NaCl dissociates into sodium ions (Na⁺) and chloride ions (Cl⁻) when it dissolves in water.
-
most likely will conduct electricity - The presence of these ions in solution allows the water to conduct electricity, as solutions containing free-moving ions can carry an electric current.
The other two options are incorrect:
- displays covalent molecule properties - NaCl is an ionic compound, not a covalent molecule.
- does not separate into ions - This is also incorrect, as NaCl does indeed separate into ions when dissolved in water.
